And it was a cake-walk. Drained the water into a large trash basket along with 6 more gallons on the side. Put the fish in the large trash can, as well. Dug out the gravel and that also went into a pail. Took out the decorations, of course. Moved the tank where I wanted it, added the water in pails, then the fish then rest of water.

wa-la. Tank totally clear again this morning. Nuttin' to it.
